Configuring Icinga Monitoring Retention Policy

This section describes how to configure and applying the retention time for Icinga Data Output (IDO) DB.

The retention time is by default set to 550 days, meaning that the data stored in IDO DB are kept for 550 days and deleted afterwards. This will affect the monitoring data history, that are used for populating SLM reports. This value can be changed at a later point, customize it based on user’s needs.

Background

In the 4.13 release a new setting has been introduced, called retention policy. The reason for its introduction is that the all data (warnings, logs, output of checks, and so on) are stored in the Database, which can dramatically grow over time. This setting will be enabled by default in new installation only, while existing installation must configure it and enable it, following the steps described next. The default value given to this setting is 550 days, but can be changed at a later point.

How To Set The Retention Time

To configure or modify the value, go to Configuration > Modules > Neteye > Configuration.

  • Step 0. Click on the slider called Enable default retention policy to enable the feature. The slider will disappear afterwards. Indeed, once the feature is enabled, there is no rolling back, it will remain enabled forever.

  • Step 1. Insert a value in days for the Default retention policy age, which by default is 550, i.e., one year.

  • Step 2. Click on the Save Changes button.

  • Step 3. Go to the command line and run the neteye install script.

Warning

Only after Step 4 the setting will be applied and enabled, so make sure to complete successfully all the steps!

How To Disable the Retention Time

The retention time can be disabled, meaning that no data will ever be deleted. To do so, set the value of retention time to 0 (zero).

Warning

Disabling the retention time is discouraged, because the disk space required by the Databases might grow quickly if the monitoring activities on NetEye create a lot of input.
